Patentan s ρ r ü c h e : 'Patent application : ' 1 . Verfahren zum Trennen von mikrobiellem i;i 1 . Method for separating microbial i; i ATP, nichtmikrobiellem ATP und extrazellularem ATP durch Hindurchleiten einer Probe, die das ATP enthält, aufwärts durch eine Reihe von Filtermembranen abnehmender Porengröße, wobei sämtliche Membranen für das extrazellulare ATP durchlässig sind, wenigstens eine Filtermembran für das mikrobielle ATP enthaltende Zellen undurchlässig ist, und wenigstens eine Filtermembran für das nichtmikrobielle ATP enthaltende Zellen undurchlässig ist, und wobei die für das nichtmikrobielle ATP undurchlässige Filtermembran stromaufwärts der für das mikrobielle ATP undurchlässigen Filtermembran angeordnet ist.ATP, non-microbial ATP and extracellular ATP by passing a sample containing the ATP upwards through a series of filter membranes of decreasing pore size, all membranes for the extracellular ATP are permeable, at least one filter membrane for the microbial cells containing ATP is impermeable, and at least one filter membrane is impermeable to the non-microbial ATP-containing cells and with the filter membrane impermeable to the non-microbial ATP upstream the filter membrane that is impermeable to the microbial ATP is arranged.
2. Verfahren zum Trennen von mehreren Zelltypen, die in einer einzelnen Probe enthalten sind, durch Hindurchleiten der Probe aufwärts durch eine Reihe von Filtermembranen abnehmender Porengröße, wobei jeder Filter gegenüber2. Method of separating multiple cell types that are in of a single sample by passing the sample upward through a series of filter membranes decreasing pore size, with each filter being opposite den anderen Filtern eine andere Porengröße hat und wobei die Filter jeweils nacheinander für alle einzelligen Organismen mit Ausnahme von einem durchlässig sind.the other filters have a different pore size and the filters one after the other for all unicellular Organisms with the exception of one are permeable. 3. Verfahren zum Trennen und Messen von zellularem ATP und extrazellularem ATP durch Hindurchleiten einer das ATP enthaltenden Probe aufwärts durch eine Reihe von Filtermembranen abnehmender Porengröße, wobei alle Membranen für das extrazellulare ATP durchlässig sind und wenigstens eine Filtermembran für das zellulare ATP enthaltende ZeI-len undurchlässig ist, Behandeln der undurchlässigen Filtermembran, die die Zellen enthält, nacheinander mit einem Lysiermittel, um das Adenosintriphosphat aus den Zellen freizusetzen, und mit einem Lumineszenzmittel, um es mit dem freigesetzten ATP reagieren zu lassen und dadurch ein Lumineszenzansprechen direkt an der Filtermembran zu erzeugen, und Messen des Lumineszenzansprechens mit einem Luminometer.3. Method of separating and measuring cellular ATP and extracellular ATP by passing a das ATP-containing sample up through a series of filter membranes of decreasing pore size, all membranes for the extracellular ATP are permeable and at least one filter membrane for the cells containing cellular ATP is impermeable, treating the impermeable filter membrane containing the cells sequentially with a Lysing agent to remove the adenosine triphosphate from the cells to release, and with a luminescent agent to make it react with the released ATP and thereby generate a luminescent response directly on the filter membrane, and measure the luminescent response with one Luminometer. 4. Verfahren zum Isolieren von im wesentlichen reinen Bakterienzellen aus einer Probe, die außerdem nichtmikrobielle, lösbare Störsubstanzen enthält, durch Hindurchleiten einer die Zellen enthaltenden Probe aufwärts durch eine Reihe von Filtermembranen abnehmender Größe, wobei sämtliche Membranen für die Störsubstanzen durchlässig sind und wenigstens eine Filtermembran für die Zellen undurchlässig ist.4. Method for isolating essentially pure bacterial cells from a sample which are also non-microbial, contains solvable interfering substances by passing a sample containing the cells upward through a series of filter membranes of decreasing size, all membranes being permeable to the interfering substances and at least one filter membrane is impermeable to the cells. 5. Verfahren zur Zellenanreicherung eines besonderen Zelltyps durch Konzentrieren des besonderen Zelltyps aus einer Probe, die mehrere Zelltypen enthält, durch Hindurchleiten der die Zelltypen enthaltenden Zellenprobe aufwärts durch eine Reihe von Filtermembranen abnehmender Porengröße, wobei wenigstens eine Filtermembran für den besonderen Zelltyp undurchlässig ist.5. A method for cell enrichment of a particular cell type by concentrating the particular cell type from a Sample containing multiple cell types by passing the cell sample containing the cell types up through a series of filter membranes of decreasing pore size, with at least one filter membrane for the particular cell type is impermeable.
